I also got a Fire Phone cheap when Amazon was selling them out. I forget what I paid. I think close to $125 but I'm not sure. It's the 32 gig model.
I've never used it for a phone. I bought it because it's built-in Kindle app allows manual scrolling, a feature I like a lot.
It's not a bad device. For what I paid for it it's a very good device. If I'd paid full price I probably would have returned it. Everything works pretty well but it's user interface is very awkward and non-intuitive and it's battery life isn't all that good. I have a bunch of videos on it along with MX Player. It's an excellent pocket size ebook reader and Audible player. It's a handy device at times.
It's big show-off feature, the 3D thingy that alters the pictures based on your viewing angle is one of the silliest features I'd ever heard of. I tried a number of it's built-in 3D wallpapers and they are kind of impressive but who cares! They're just wallpapers. They had to add some fairly expensive hardware to make that work, to say nothing of developer's time. I've often said that the new Nook Glowlight Plus's capacative Home button was the dumbest design feature in tech history and I still think so but that 3D Fire phone feature is surely number 2.
